2 Claims.

The invention relates to water closets and more particularly to the Construction of a flushing rim for the bowl. In the present state of the art it is quite common to provide the bowl of water i closets with flushing rims through which the water discharged from the flushing tank is directed against the side walls of the bowl. With certain types of water closet the greater portion of the water used in flushing is admitted to the bowl below the water seal and only suflicient water is discharged through the rim to wash the sides of the bowl. My improvement relates more particularly to this latter type of water closet and has for its object First, the more uniform distribution of water around the rim and the more uniform discharge from the rim at all points therearound so that with a limited quantity of water all sides of the bowl are effectively washed;

Second, the obtaining of a noiseless operation;

Third, the imparting to the water discharged into the bowl a spiral direction, so as not to interfere with the rotation of the water in the bowl imparted by the main supply. 4

With these and other objects in View the invention consists in the Construction as hereinafter set forth.

In the drawing:

Fig. 1 is a plan View partly in horizontal sec tion through the rim of the bowl;

Fig. 2 is a side elevation partly in vertical sectionthrough the rim;

Fig. 3 is an enlarged cross section through the rm;

Figs. 4 and 5 are respectively a horizontal section on the line '5-5 and a vertical section on the line 4-4 of Fig. 3.

With the type of water closet for which my improved rim is particularly designed as above referred to the tank is formed integral with the' bowl and as before stated the greater portion of the water for flushing the bowl is introduced therein from the tank at a point below the water seal. The water for the rim flush is not obtained from the tank, but is supplied directly from the ball cock during the interval in which the tank is discharging and refilling. The particular fittings for accomplishing this function form no part of the present invention, but the rim is so constructed as to provide for connection therewith. As shown, A is the bowl which at its upper end is provided with a hollow rim B and which has also integral therewith the ushing tank C. In the manufacture of the closet the rim B is first molded independent of the bowl and is then integrated therewith, being provided with a -top portion B' united with the top of the bowl along the dotted line B* and extending radially inward therefrom. Also a depending portion B and an outwardly turned portion B which together form an annular channel D between the rim and the bowl. The portion B is also integrated with the bowl at points of contact therewith but has molded therein a series of obliquely extending jet passages E. These as shown in Figs. 4 and 5 are of obtuse angular form in horizontal section and` in vertical section incline downward in a direction opposed to the direction of flow of water through the channel D. As these passages E are all molded into the rim'they are uniform in size and shape, so that the amount of water discharged therethrough on one side of the bowl is equal to that on the other side. Also, as the outer wall of the passage E is formed by the bowl itself, all of the water discharged through the passage will be directed against and will adhere to the wall of the bowl.

At one point in the rim there is formed inte* gral therewith a water inlet conduit F which is arranged within the tank C and extends rearwardly therein. At its rear end this conduit has a flaring portion F' adapted to engage the connection from theball cock. At its forward end the conduit F is curved to extend tangent to the channel D so that the water flowing through this conduit will be directed around the rim to a point adjacent to the point of entrance. Here the channel D terminates, being separated by the wall F from the conduit F. There is, however, a vent passage G which connects the upper portion of the end of the passage D with the tank C, permitting escape of air during the interval in which the channel D is filling with water, and after filling discharging a small quantity of water therethrough into the tank C. g

As has been stated, the downward inclination of the ports E is in a direction opposed to the flow of water through the channel D. By reason of this arrangement when water is first admitted through the conduit F into the channel D it will pass around said channel without discharging through the ports E. A portion of the air which is Originally in the channel D may be displaced through these ports E, but if this alone were depended upon, the fiushing operation through the rim would be very noisy. The reason for this is probably that commingled air andwater would be discharged through the ports, which is always accompanied by a noise. I have, however, avoidedthis difiiculty by the vent port G at the end of the channel, which permits escape of air after the scaling of a portion or all of the ports E, so that the entire channel F will be filled with water before discharge from the ports E begins. Such discharge will then be noiseless, for solid streams of water will flow through each of the ports E and in contact with the inner face of the bowl.

What I claim a's my invention is:

1. A water closet comprising a bowl, an integral fiushing tank and a channeledrim for the bowl extending therearound,-the channel of said rim being provided with a water inlet connection and having a dead opposite end, water discharge ports distributed around said rim inclining downward therefrom in a direction opposite to the flow of water through the channel, andan air vent at the dead end of said channel connecting with the portion thereof last to be filled with water and directing water discharged therethrough into said tank.

2. A water closet comprising a bowl, an integral fiushing tank and a channeled rim for the bowl, the channel of said rim being provided with a water inlet connection and having a dead end, downwardly directed water discharge ports distributed around said rim, and an air vent at the dead end of said channel c-onnecting with the portion thereof last to be filled with water and -directing the water discharged therethrough into
